My wife and I stayed at Emeralda for three nights in June, 2019 and it was a highlight of our three week trip to Vietnam. The hotel is set on beautiful grounds, with nature all around. It is quiet and peaceful, with beautiful paths for birding around their pools and grounds. The hotel room we stayed in was perfect: a bungalow next to a private pool. Everything in the room was modern and clean and the bed and air conditioning were perfect. The hotel has a very good restaurant on the property with excellent choices for dinner in a relaxed, beautiful atmosphere near their main pool area. There is even an indoor pool with water that was refreshing and perfect for the hot days to relax. The breakfast buffet is excellent with a huge selection of choices. The food was all excellent and fresh. The best part of this hotel is the staff - incredibly helpful and kind. They were available day or night and were always gracious and helpful. I want to particularly highlight the hotel's manager, Einda - she was so kind, so helpful and always smiling in our direction. She is amazing. Also, our guide for our day trip was Dung, an excellent, friendly guide, also connected to the hotel staff. He was knowledgable, with excellent English and so kind and flexible with us. My wife also had a wonderful massage at their Spa. All of this made for a superb, relaxing and enlightening part of our Vietnam trip and we thank everyone at this superb hotel! The best place to stay in Ninh Binh!
